WHAT DOES THEORETICAL PROBABILITY MEAN HOW DO I WORK IT OUT?

The ultimate task of all the explorations launched by the Europeans from the fourteenth century onward was? A. finding a sea link between Europe and the wealthy civilizations of Asia. B. establishing European political dominion over all of Asia. C. perfec...

A car is climbing a hill and accelerating at a constant rate of 0.3 g as it does so. Φ=10°. What is the steady state value of θ, the angle made by a mass hung from a cord that’s attached to the rearview mirror. ?

A particular microwave oven operates at 1000W. The wavelength of the microwave is 12.0cm. You decide that you like your snack to absorb 1.2 x 10^28 photons. For how much time should you have the oven on- with your snack inside of course. Assume 100% effic...

The lowest temperature ever recorded in Alaska is-6 C. The highest temperature ever recorded in Alaska is 38°C. Suppose a piece of metal with a mass of 180 g and a temperature of -62.0°C is placed in a calorimeter containing 0.500 kg of water with a tempe...

[Sin^2(theta) - tan(theta) ] / [cos^2(theta) - cot(theta)] = tan^2(theta) I am supposed to prove that the left side of the equation is supposed to be equal to the right side. And I been confused on how to solve it.

[1 + sin(theta) + cos(theta)] / [1 + sin(theta) - cos(theta)] = [1+cos(theta)]/ sin(theta)

what electric field strength would be required to suspend an alpha particle? (contains 2 protons and 2 neutrons) The answer should be 2.05 x 10^-7 N/C. I am not given distance so I am not sure how I should solve this particle problem.

I guess I will answer my own question so, if others come across it, it will help PT/h(lamda) P: power T: time (which is the variable in this case) h: (constant 6.626x10^-34) c: lamda is found by c/f in which, c= 3x10^8 frequency= .12 in this case if you s...

I forgot to include that the answer is 130 J/kg x Celsius

Thanks for teaching me how to solve my trig problems. I had trouble with those two and your explanations guided me how to solve these types of problems. :)

When we move vertically upward from the earth, the temperature decrease up to th stratosphere and again increases and we fe difficulty in breathing in as the presences of oxygen disappears after the troposphere.
